I guess I'll bite on the thread.
Lawnmower is a small simple Husqvarna, liked it because it didn't have one of those newer EX series engines that is 'top and go' on the oil. As far as I am concerned, the only engines that should be designed to consume oil naturally are Rotary.
The 550EX B&S Motor is simple, efficient and easy to get parts for if required. Though I normally prefer Honda engines (quieter, usually better built) I've been sorely tested at some of their design issues on the Lawn Boy series (I've fixed the 3 at work too many times now), so that steered me back to B&S (My Murray made it 16 years with one of those motors, and it was the Deck that eventually rotted it, it still started on its dying day).
Power Tools? Stihl. 100 % born and raised that way. The Chainsaw at the cottage is from the 70's and it still works (and let me tell you, we have NOT treated that thing well over the years).
I have an FS56, BS56 and MS170. All running on 91.
They start, and just work. I can leave the fuel in over the fall into winter (2 year Open shelf life). And it has never caused an issue to this day. I love their hardware, and service level I get.
